Borked Grub2 on trying to update to f32

Upgrading from Fedora 30 to 32. Downloaded via DNF and started the install via reboot. The install did not show up in the grub menu. Just the previous versions of Fedora 30. Saw that there was a know issue with F30 and tried to fix it per the instructions. In the process I totally screwed it up grub.

Currently if I boot all I get is the Grub Rescue prompt. Currently using the live USB.

I have tried to fix it using the procedures on the following pages


Neither of these worked due to paths not being viable.

Also tried Rescatux. It failed.

I think the issue is down to what I have set up in my software raids.
Setup of drives

Note I’m a not very good with using the command line. So specific commands are helpful that I can use to fix this from a Fedora 32 live USB.

Let me know what other information is needed.

Just for your information, the upgrade process does not show up as a line item in Grub2. You simply boot your last kernel (F30 in your case) and then the upgrade process will be triggered.

Follow the instructions:
Restoring the bootloader using the Live disk

Paste the whole console log, so we can understand which step you fail to complete and why.

I never get past step 5. I don’t think I have the directories correct but not sure what to use

From what I remember I set up drives for boot, home (raid), swap (raid) and linux(raid).

Thanks for all the help

What method did you use to create the RAID?

In addition, check the output:

lsblk -o +FSTYPE,UUID /dev/mapper/fedora-*

raid was set up with the graphical user interface that is part of the fedora installer several years ago (or many).

These are Ext4 volumes, you can try to mount them and see what’s there.

Also check if there’s any file system on md125, md126, md127:

lsblk -o +FSTYPE,UUID

If there’s no, then your RAID has probably fallen apart, so you need to re-assemble it:

If you followed that script exactly while booted from the live F32 usb then that might be what borked Grub2. Your post of the steps you followed above show that the recovery procedure you were following expected the root filesystem to be on an LVM partition. I believe your system has the root filesystem on /dev/sda1.

Please note that posted procedures expect the user to be familiar with their system and to not blindly follow along since doing so blindly can easily make a system unrecoverable. Take time to familiarize yourself with the system and the contents of each device.

The command at the end of that script is for a system is using MBR and /dev/sda is the proper location for the boot sector.
Note that /dev/sda is a device and NOT a filesystem partition. Writing anything other than an MBR boot record there can screw up the entire drive.

F32 is a 64 bit system only and cannot be used to upgrade an already installed 32 bit system as has been noted several times in this forum. Your currently installed system appears to be a 32 bit system since all the drives show as “Disklabel type” “dos” in your fdisk output above. It seems likely that you will need to do a new install.

Try booting from an F30 live usb and then do the grub repair steps noted in the pages you quoted.

New installs can easily be done while saving your personal data by making sure that you reuse the existing filesystem(s) you want and do not format it(them). You will need to format the root filesystem and all its system areas under (if there is something in /home you want to keep then do a backup before you do the reinstall. I do not see a separate /home filesystem.)

I do not think it likely that your raid is an issue since it shows well in the outputs you provided.

posting the results of “cat /etc/fstab” can give us more information on your system configuration.

I’ll try the F30 live USB to fix Grub

If I do a clean install will it fix grub?

Note md125 & md126 are already mounted in the fedora live and have files in each. md125 has my home directory. md126 has operating system.

Good, and here is your swap:

Also, did you check these volumes?

Could they be related to the boot?

Actually, there’s another one looking suspicious:

I remember setting up a small partition on each drive. the one on Sda1 was for boot. The other two where to make the drives symmetrical but I never used them. (Each drive had a 1Gig partition, then raids for the rest of the drive for md125, md126 & md127.)

Ok, I think, you can proceed with the recovery:

  • boot - sda1
  • root - md126

when I get to step 5 in the reinstall of grub this command doesn’t work. How do I modify them to correctly work with my setup.

Step: 5 mount /dev/mapper/fedora-root /mnt/root

Change that to “mount /dev/md126 /mnt/root”
then do an “ls /mnt/root” to verify the correct file structure before you go on.
You should see something like

 bin  boot  dev  etc  home  lib  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var  

You will also need to do

mount /dev/sda1 /mnt/root/boot
in order to have the entire system directory structure mounted to do the repair

This got me past step 5. Once I download a F30 live USB i’ll continue. (I don’t want to bork it up any more with 32bit vs 64bit.) I’ll deal with the upgrade a bit later.

I’ll report back once I’ve completed this.

The procedure got me to the Grub Prompt. Yey. Can you recommend the correct procedure to boot fedora with my drive setup. (I’m a little gun shy at this point to try any of these)

Thanks for all the help so far. It is greatly appreciated.

Check from the live chroot:

cat /etc/default/grub
grep -v -e ^# -e ^$ /etc/fstab
sudo grub2-editenv list
